vhnience of illustration; Fig. 3 is a perspec- This invention particularly relates to mixing devices which are actuated'by shaking, and is especially directed to vessels for mix- The principal objects of this invention are, to provide a mixing vessel that may be conveniently manipulated by one hand of the operator; to provide a mixing vessel that'may be readily cleansed; and to provide a mixing vessel with means arranged to retain any solid or coagulated particles therein, when pouring the contents therefrom.

Other objects of this invention are, to provide a mixing vessel with readily removable and adjustable end closures forming seals for said vessel; and to provide said vessel with a movable strainer having means to prevent its accidental displacement when in operative position. 7

A further object of this invention is, to provide a double frusto-coni'cal mixing vessel having walls converging toward its opposite ends from a central region of maximum diameter, .whereby its efficiencyas a mixer is greatly enhanced.

This invention also comprehends all of the various novel features of construction and arrangement hereinafter more definitely specified. I v In the accompanying drawings, Figure 1 is a central longitudinal sectional view of the preferre'dform of this invention, shoW-' ing. a mixer having astrainer in its inoperative position; Fig. 2 1s a plan sectional view of saidmixer taken on the line 2 2 in Fig.

and Fig. 6 is a fragmentary sectional elevation, showlng an alternative means of attaching the closures to the body of the mix-- ing vessel.

In said figures, the frusto-conica'l hollow body 10 of the mixing vessel is preferably composed of separately formedfrusto-conical shells 11 and 12, having their larger peripheral edges 13 andlt overlapped and permanently secured together by any convenient means, preferably by solder. vessel body 10 thus formed is provided with openings 15 and l6-at its respectively opposite ends, which are provided with detachable closures 18 and 19, which are respectively provided with screw threads 20 The Patented Mar. 4, 1913.

and 21 conveniently rolled in their flaring.

walls 22 and 23, near their peripheral edges, and arranged to engage the screw threads 24 and 25 in the shells 11 and 12 adjacent to said openings 15 and 16. The closures are each provided with an annular ridge 28 cooperative with their respective walls 22 and 23 to form a groove 29 in the angle of the closure, for the reception of the edge of the vessel body, and as best shown in-Fig. 5,"

said ridge provides a beveled surface 30 ar-' ranged to cooperate with the beveled surface 32 at the edges of the respective shells 11 and 12, whereby an absolutely fluid-tight joint is effected when the threads 20 and-21 of the respective closures are engaged with the threads 24 and 25 of the vessel body, and

said threads may be so arranged that a partial rotation of the closures 18 and 19 will-- effect suchc'o operation of the closures with the ends of-the vessel body as to effect the absolutely fluid-tight joint desired.

In order to retain the solid or coagulated particles within the mixing vessel when pouring the fluid therefrom, the mixing vessel is provided with a strainer 35, com

prising the foraminous diaphragm 36 having oppositely disposed lips 37 and 38.

Said strainer is provided with the rock shaft 39 forming at one enda trunnion 40 for engagement in the socket bearing 5L1 in the wall of the vessel body 10, and a trunnion 4:2 mounted in the bearing sleeve 43 disposed in diametrically opposite relation to the socket bearing 41 in-said vessel body. Said rock-shaft 39 is extended through the bearing 43. and is provided with a thumbpieoe' 45 for conveniently rotating; the 110 strainer within'the mixing vessel. As best shown in Fig. 4, the lips 37 and 38' are arranged to engage the walls of the vessel body 10 when in its operative position, and

by such engagement said strainer is prevented from accidental rotation by the ice or other heavy solid particles contained in the vessel body behind said strainer 35,

whereby when it is desired to pour the con mixing vessel in the form of a double conical frustum, the-material to be mixed is brought together atithe restricted ends of j the vessel, and is therebymore efficiently mixed than if the mixing vessel were formed cylindrical, and that by rigidly connecting the parts as herein contemplated,

the operator is enabled to manipulate the mixer with one hand.

It is not desired to limit this. invention tothe precise details of construction and ar- .rangement herein set forth, as various modifications may be-made therein without de- .p'arti-ng from the essential features of the.

V invention as defined in the appended claims.

1. A mixing vessel comprising a double.

frusto-conical hollow, body having opposite for said open ends detachably engaged with said body, and

I as

body having openings in its and closures detachably engaged with said' having means comprising a groove cooperative with the edge of said body to seal the joint between said body and closures.

, 2. A mixing vessel comprising a hollow bodyhaving open ends, and closures for said ends provided with a ridge, forming a channel to receive the edges of said body, and cooperating with said edge'to seal the joint between said body and closures.

3. A mixing vessel comprising a hollow opposite ends,

body, each provided with a ridge having a "beveled edge for cooperative engagement with the peripheral edges e f-said body.

4; A'mixing vessel comprising a hollow body having opposite open ends provided with beveled edges, and closures forsaid open ends, each provided with a ridge having a beveled surface cooperative with the beveled edges of said body to seal the between said bodyand closure. I

twill obvious that by providing a site directions body having opposite open ends, and a rotatable strainer disposed local to one of said ends, and having means extending exterior to said body for rotating said strainer.

7. A mixing vessel comprising a hollow body, and a strainer mounted for rotation therein, and comprising a foraminous diaphragm' having lips engageable with the walls of said body, to prevent accidental rotation when in operative position.

. 8. A mixing vessel comprising a hollow body, a strainer mounted to rotate in said body on an axis transverse to the axis of said body, and comprising a foraminous diaphragm having oppositely disposed lips arranged to engage the wallsjof said body, to prevent its accidental rotation when in operative position, and means to manipulate said strainer.

9. A mixing vessel comprising a hollow body having openings in its opposite ends, detachable closures for-said openings, and a strainer disposed nearer to one end than the other, and comprising a foraminous diaphragm, and a rock-shaft for said diaphragm having a thumb-piece extending exterior to said body for its convenient manipulation.

10. A mixing yessel comprising a hollow body having opposite open ends, closures .for the openings in said ends, detachably engaged with saidbody, and a strainer mounted to rotate adjacent to one of said openings on an axis transverse to the axis of said body, and comprising a foramiilous diaphragm having'lips extending in oppowith respect to said diaphragm from the diametrically opposite sides thereof, and a rock-shaft for sald dia-- .phragm. having a thumb-piece projecting 1 exterior to said body for the convenient rotation of said strainer. p
